1Multiple Cash Flows –Future Value Example 6.1 Find the value at year 3 of each cash flow and add them together.Today (year 0 CF): 3 N; 8 I/Y; PV; CPT FV =Year 1 CF: 2 N; 8 I/Y; PV; CPT FV =Year 2 CF: 1 N; 8 I/Y; PV; CPT FV = 4320Year 3 CF: value = 4,000Total value in 3 years = = 21,803.58Value at year 4: 1 N; 8 I/Y; PV; CPT FV = 23,547.87
2Multiple Cash Flows – FV Example 2 Suppose you invest $500 in a mutual fund today and $600 in one year. If the fund pays 9% annually, how much will you have in two years?Year 0 CF: 2 N; -500 PV; 9 I/Y; CPT FV =Year 1 CF: 1 N; -600 PV; 9 I/Y; CPT FV =Total FV = =Formula: FV = 500(1.09) (1.09) =
3Multiple Cash Flows – Example 2 Continued How much will you have in 5 years if you make no further deposits?First way:Year 0 CF: 5 N; -500 PV; 9 I/Y; CPT FV =Year 1 CF: 4 N; -600 PV; 9 I/Y; CPT FV =Total FV = =Second way – use value at year 2:3 N; PV; 9 I/Y; CPT FV =Formula:First way: FV = 500(1.09) (1.09)4 =Second way: FV = (1.09)3 =
4Multiple Cash Flows – FV Example 3 Suppose you plan to deposit $100 into an account in one year and $300 into the account in three years. How much will be in the account in five years if the interest rate is 8%?Year 1 CF: 4 N; -100 PV; 8 I/Y; CPT FV =Year 3 CF: 2 N; -300 PV; 8 I/Y; CPT FV =Total FV = =FV = 100(1.08) (1.08)2 = =
7Multiple Cash Flows – PV Another Example You are considering an investment that will pay you $1000 in one year, $2000 in two years and $3000 in three years. If you want to earn 10% on your money, how much would you be willing to pay?N = 1; I/Y = 10; FV = 1000; CPT PV =N = 2; I/Y = 10; FV = 2000; CPT PV =N = 3; I/Y = 10; FV = 3000; CPT PV =PV = =Formula:PV = 1000 / (1.1)1 =PV = 2000 / (1.1)2 =PV = 3000 / (1.1)3 =
8Annuities and Perpetuities Defined Annuity – finite series of equal payments that occur at regular intervalsIf the first payment occurs at the end of the period, it is called an ordinary annuityIf the first payment occurs at the beginning of the period, it is called an annuity duePerpetuity – infinite series of equal payments
9Annuities and Perpetuities – Basic Formulas Perpetuity: PV = C / rAnnuities:
10Annuities and the Calculator You can use the PMT key on the calculator for the equal paymentThe sign convention still holdsOrdinary annuity versus annuity dueYou can switch your calculator between the two types by using the 2nd BGN 2nd Set on the TI BA-II PlusIf you see “BGN” or “Begin” in the display of your calculator, you have it set for an annuity dueMost problems are ordinary annuities
11Annuity – Example 6.5You borrow money TODAY so you need to compute the present value.48 N; 1 I/Y; -632 PMT; CPT PV = 23, ($24,000)Formula:
12Annuity – Sweepstakes Example Suppose you win the Publishers Clearinghouse $10 million sweepstakes. The money is paid in equal annual installments of $333, over 30 years. If the appropriate discount rate is 5%, how much is the sweepstakes actually worth today?30 N; 5 I/Y; 333, PMT; CPT PV = 5,124,150.29Formula:PV = 333,333.33[1 – 1/1.0530] / .05 = 5,124,150.29
13Buying a HouseYou are ready to buy a house and you have $20,000 for a down payment and closing costs. Closing costs are estimated to be 4% of the loan value. You have an annual salary of $36,000 and the bank is willing to allow your monthly mortgage payment to be equal to 28% of your monthly income. The interest rate on the loan is 6% per year with monthly compounding (.5% per month) for a 30-year fixed rate loan. How much money will the bank loan you? How much can you offer for the house?
14Buying a House - Continued Bank loanMonthly income = 36,000 / 12 = 3,000Maximum payment = .28(3,000) = 84030*12 = 360 N.5 I/Y840 PMTCPT PV = 140,105Total PriceClosing costs = .04(140,105) = 5,604Down payment = 20,000 – 5604 = 14,396Total Price = 140, ,396 = 154,501
15Finding the PaymentSuppose you want to borrow $20,000 for a new car. You can borrow at 8% per year, compounded monthly (8/12 = % per month). If you take a 4 year loan, what is your monthly payment?4(12) = 48 N; 20,000 PV; I/Y; CPT PMT =Formula20,000 = PMT[1 – 1 / ] /PMT =
16Finding the Number of Payments – Example 6.6 The sign convention matters!!!1.5 I/Y1000 PV-20 PMTCPT N = MONTHS = 7.75 yearsAnd this is only if you don’t charge anything more on the card!You ran a little short on your spring break vacation, so you put $1000 on your credit card. You can only afford to make the minimum payment of $20 per month. The interest rate on the credit card is 1.5 percent per month. How long will you need to pay off the $1,000.
17Finding the Number of Payments – Another Example Suppose you borrow $2000 at 5% and you are going to make annual payments of $ How long before you pay off the loan?Sign convention matters!!!5 I/Y2000 PVPMTCPT N = 3 years2000 = (1 – 1/1.05t) / .05= 1 – 1/1.05t1/1.05t == 1.05tt = ln( ) / ln(1.05) = 3 years
18Finding the RateSuppose you borrow $10,000 from your parents to buy a car. You agree to pay $ per month for 60 months. What is the monthly interest rate?Sign convention matters!!!60 N10,000 PVPMTCPT I/Y = .75%
19Future Values for Annuities Suppose you begin saving for your retirement by depositing $2000 per year in an IRA. If the interest rate is 7.5%, how much will you have in 40 years?Remember the sign convention!!!40 N7.5 I/Y-2000 PMTCPT FV = 454,513.04FV = 2000( – 1)/.075 = 454,513.04
20Annuity DueYou are saving for a new house and you put $10,000 per year in an account paying 8%. The first payment is made today. How much will you have at the end of 3 years?2nd BGN 2nd Set (you should see BGN in the display)3 N-10,000 PMT8 I/YCPT FV = 35,061.122nd BGN 2nd Set (be sure to change it back to an ordinary annuity)Formula:FV = 10,000[(1.083 – 1) / .08](1.08) = 35,061.12What if it were an ordinary annuity? FV = 32,464 (so receive an additional by starting to save today.)
21Annuity Due Timeline32,464If you use the regular annuity formula, the FV will occur at the same time as the last payment. To get the value at the end of the third period, you have to take it forward one more period.35,016.12
22Perpetuity – Example 6.7 Perpetuity formula: PV = C / r Current required return:40 = 1 / rr = .025 or 2.5% per quarterDividend for new preferred:100 = C / .025C = 2.50 per quarterSuppose the Fellini Co. wants to sell preferred stock at $100 per share. A very similar issue of preferred stock already outstanding has a price of $40 per share and offers a dividend of $1 every quarter. What dividend will Fellini have to offer if the preferred stock is going to sell.
23Effective Annual Rate (EAR) This is the actual rate paid (or received) after accounting for compounding that occurs during the yearIf you want to compare two alternative investments with different compounding periods you need to compute the EAR and use that for comparison.
24Annual Percentage Rate This is the annual rate that is quoted by lawBy definition APR = period rate times the number of periods per yearConsequently, to get the period rate we rearrange the APR equation:Period rate = APR / number of periods per yearYou should NEVER divide the effective rate by the number of periods per year – it will NOT give you the period rate
25Computing APRs What is the APR if the monthly rate is .5%? .5(12) = 6%What is the APR if the semiannual rate is .5%?.5(2) = 1%What is the monthly rate if the APR is 12% with monthly compounding?12 / 12 = 1%Can you divide the above APR by 2 to get the semiannual rate? NO!!! You need an APR based on semiannual compounding to find the semiannual rate.
26Things to RememberYou ALWAYS need to make sure that the interest rate and the time period match.If you are looking at annual periods, you need an annual rate.If you are looking at monthly periods, you need a monthly rate.If you have an APR based on monthly compounding, you have to use monthly periods for lump sums, or adjust the interest rate appropriately if you have payments other than monthly
27Computing EARs - Example Suppose you can earn 1% per month on $1 invested today.What is the APR? 1(12) = 12%How much are you effectively earning?FV = 1(1.01)12 =Rate = ( – 1) / 1 = = 12.68%Suppose if you put it in another account, you earn 3% per quarter.What is the APR? 3(4) = 12%FV = 1(1.03)4 =Rate = ( – 1) / 1 = = 12.55%
28EAR - Formula Remember that the APR is the quoted rate m is the number of compounding periods per year
29Decisions, Decisions IYou are looking at two savings accounts. One pays 5.25%, with daily compounding. The other pays 5.3% with semiannual compounding. Which account should you use?First account:EAR = ( /365)365 – 1 = 5.39%Second account:EAR = ( /2)2 – 1 = 5.37%Which account should you choose and why?Rates are quoted on an annual basis. The given numbers are APRs, not daily or semiannual rates.
30Decisions, Decisions I Continued Let’s verify the choice. Suppose you invest $100 in each account. How much will you have in each account in one year?First Account:365 N; 5.25 / 365 = I/Y; 100 PV; CPT FV =Second Account:2 N; 5.3 / 2 = 2.65 I/Y; 100 PV; CPT FV =You have more money in the first account.
31Computing APRs from EARs If you have an effective rate, how can you compute the APR? Rearrange the EAR equation and you get:
32APR - ExampleSuppose you want to earn an effective rate of 12% and you are looking at an account that compounds on a monthly basis. What APR must they pay?
33Computing Payments with APRs Suppose you want to buy a new computer system and the store is willing to sell it to allow you to make monthly payments. The entire computer system costs $3500. The loan period is for 2 years and the interest rate is 16.9% with monthly compounding. What is your monthly payment?2(12) = 24 N; 16.9 / 12 = I/Y; 3500 PV; CPT PMT =
34Future Values with Monthly Compounding Suppose you deposit $50 a month into an account that has an APR of 9%, based on monthly compounding. How much will you have in the account in 35 years?35(12) = 420 N9 / 12 = .75 I/Y50 PMTCPT FV = 147,089.22
35Present Value with Daily Compounding You need $15,000 in 3 years for a new car. If you can deposit money into an account that pays an APR of 5.5% based on daily compounding, how much would you need to deposit?3(365) = 1095 N5.5 / 365 = I/Y15,000 FVCPT PV = -12,718.56
36Pure Discount Loans – Example 6.12 Treasury bills are excellent examples of pure discount loans. The principal amount is repaid at some future date, without any periodic interest payments.If a T-bill promises to repay $10,000 in 12 months and the market interest rate is 7 percent, how much will the bill sell for in the market?1 N; 10,000 FV; 7 I/Y; CPT PV =PV = 10,000 / 1.07 =
37Interest-Only Loan - Example Consider a 5-year, interest-only loan with a 7% interest rate. The principal amount is $10,000. Interest is paid annually.What would the stream of cash flows be?Years 1 – 4: Interest payments of .07(10,000) = 700Year 5: Interest + principal = 10,700This cash flow stream is similar to the cash flows on corporate bonds and we will talk about them in greater detail later.
38Amortized Loan with Fixed Payment - Example Each payment covers the interest expense plus reduces principalConsider a 4 year loan with annual payments. The interest rate is 8% and the principal amount is $5000.What is the annual payment?4 N8 I/Y5000 PVCPT PMT =
